Bung



Jan. 21, 193. E. A. RASBRIDGE 2 BUNG I Filed Nov. 6, 1935 a e/WM Z1 7,Ziadin/afc Patented Jan. 21, 1936 UNITED STATES PATENT OFFICE 3 Claims.

My invention relates to bungs for beer kegs and similar containers andhas for its principal object to provide a sleeve permanently fitted. inthe bung opening and having an internal bushing adjacent its outer endto form a liquid tight seal for the tap when inserted in the sleeve andalso including a removable plug at the inner end of the sleeve to beknocked out by the siphoning rod of the tap.

Beer taps at present are manufactured in various sizes and diflicultyhas been experienced in furnishing kegs with bungs suitable foracccommodating all types of taps and the present im-' provement has beendesigned to provide a standard bung having a removable plug capable ofuse with taps of different sizes and at the same time insuring a liquidtight seal for the tap.

Another object is to provide a bung having an internal shoulder forminga stop for the tap and thus limiting the penetrating movement of the tapin advance of striking the removable plug whereby to prevent removal ofthe plug until the tap has been properly fitted in the bung.

An additional object of the invention is to provide a bung of simple andpractical construction, which is inexpensive to manufacture andotherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation more fully hereinafter described and claimed, reference beinghad to the accompanying drawing forming part hereof wherein likenumerals refer to like parts throughout, and in which,

Figure l is a fragmentary sectional view of a keg showing my improvedbung in position and ready to have the plug knocked in by the tap rod;

Fig. 2 is a longitudinal sectional view of the bung sleeve; and

- 49 Fig. 3 is an end view thereof.

Referring now to the drawing in detail, wherein for the purpose ofillustration I have disclosed a preferred embodiment of my invention,the numeral 5 designates a beer keg having a bung opening 6 and withinwhich is permanently secured a metallic sleeve 1. The bore of the sleeveis stepped to provide sections having successively reduced diameters asindicated at A, B and C, the outer and larger section A accommodating apacking 50 ring or bushing 8 of cork or similar material to provide aliquid tight seal about the tap 9 when the latter is driven therein.

The section A of the sleeve as well as the bushing 8 is slightly taperedto insure a tighter fit for the tap, the shoulder l0, defining thesections A and B serving as a stop for the inner edge of the bushing.

The shoulder ll defining the sections B and C 60 serves as a stop forthe tap to prevent penetration thereof beyond the section B and thusseparates the tap from a plug l2 which is fitted in the inner end of thesleeve. This plug may then be driven out of the sleeve and into the kegby the rod I3 of conventional construction forming a part of the tap andwhich is slidably carried 5 thereby. The shoulder II is preferablybevelled to act as a guide for the rod l3 during the driving action.

It is believed the manner of use of the device and its advantages willbe readily apparent to 10 those skilled in the art from the foregoing.The tapering bushing 8 will accommodate the various sizes of taps in useat present and permit the driving of the tap into the bung to insure aliquid tight fit therein before the plug I2 is removed. 15 Therod l3,which is slidable in the tap is then forced against the plug to drivethe latter into the keg whereupon the contents may be withdrawn in theusual manner.

While I have disclosed a preferred embodiment 20 of my invention it isobvious that certain changes in construction may be made withoutdeparting from the spirit of the invention or the scope of the appendedclaims.

Having thus described my invention, what I 25 claim is:

1. A bung for kegs comprising a sleeve fitted into the bung opening ofthe keg and capable of receiving a tap device including a siphoning rod,the bore of said sleeve having a plurality of 30 shoulders definingsections of successively reduced diameters, a packing bushing fitted insaid outermost section, a removable plug in the innermost section of thesleeve to be driven into the keg by the siphoning rod, one of saidshoulders 35 constituting a stop for the inner end of the tap and saidshoulder further being bevelled to guide the siphoning rod into theinnermost section. to contact the plug.

2. A bung for kegs comprising a sleeve fitted into the bung opening ofthe keg and capable of receiving a tap device, a plurality of stopsspaced longitudinally in the bore of the sleeve,

a packing bushing having one edge abutting one of the stops to limitinward movement thereof, the other of said stops being engaged by thetap to limit inward movement thereof and a removable plug in the sleeveto be driven into the keg upon contact by an element of the tap.

3. A bung for kegs comprising a sleeve fitted into the bung opening ofthe keg capable of receiving a tap device, the latter including asiphoning rod, said sleeve having a bore extending therethrough with oneend enlarged, a packing bushing in said enlarged end, a removable plugin the other end of the bore to be driven into the keg upon contact bythe siphoning rod and stop means in the bore between the bushing. andthe plug to limit inward movement of the tap device.
